The planet, which is 13 times bigger than #Earth, is orbiting a star called #LHS3154, which is nine times smaller than the #sun. The planet’s heft is unremarkable in its own right, but its pairing with an ultracool #DwarfStar, the smallest and coldest stars in the universe, has puzzled scientists.

Orbiting the cool #DwarfStar K2-18, the exoplanet, 2.6 times the radius of #Earth, lies in what #Nasa calls the habitable zone, a region around a star where planets with liquid #water may be present.

For the first time, astronomers have detected a radiation belt around a dwarf star outside our solar system. Radiation belts are zones of energetic particles trapped by a planet’s or star’s magnetic field. The discovery could help us understand how radiation belts form and evolve.

Could these radio signals mean there are signs of alien life out there?
